There are plenty of ultra-lightweight gaming mice in our best gaming mice picks — but there aren't any that have a built-in hand cooler.

Pulsar recently released a collaboration with infamous air-cooling advocate Noctua — a beige and brown mouse full of top-tier hardware and holes and a built-in 40mm NF-A4x10 fan. For cooling your hand, not the hardware. This eSports-oriented gaming mouse features Pulsar's XS-2 sensor, which has a maximum resolution of 42,000 DPI and a maximum speed of 800 IPS, and can handle up to 70 G's of force. It also features up to an 8,000 Hz polling rate, and, of course, the built-in fan. It retails for the same price as the original Feinmann F01 gaming mouse, which is to say, it's pretty pricey at $179.99.

Design and Comfort of the F01 Noctua Edition

The F01 Noctua Edition is a lightweight wireless eSports gaming mouse with an ergonomic right-handed shape and a hole-filled chassis with a built-in fan. It comes in Noctua's signature beige-and-brown color scheme: The top part of the chassis is light beige, while the bottom and accents (side buttons, scroll wheel, Noctua's logo plate, and some interior elements) are brown.

The F01 Noctua Edition has a right-handed, ergonomic shape with contoured primary mouse buttons and an off-center hump. It's a little smaller than most mainstream gaming mice, measuring 4.79 inches (121.7mm) long by 2.62 inches (66.5mm) wide and 1.7 inches (43.3mm) high at its thickest point. It weighs 2.57 ounces (73g), which is on the heavier side for what is supposed to be an ultra-lightweight eSports mouse. It's about an ounce heavier than the regular Pulsar Feinmann F01, which weighs 1.62 ounces (46g), thanks to the built-in fan.

The mouse features a matte chassis made of a carbon composite material for durability. The chassis is full of holes, but at least they serve a purpose (sort of) other than reducing weight and triggering your trypophobia: they're also there to keep your hand cool. In the center of the mouse you'll see a mini Noctua fan that directs air upward — toward your palm. You can activate this fan by holding down both side buttons and scrolling up. There are four different fan speeds, indicated by the small LED indicator light on the left side of the mouse, which you can cycle through by scrolling up or down with both. Holding down both buttons and scrolling down turns the fan off.

Button-wise, it's pretty standard: primary mouse buttons, two side buttons, a power button / DPI switch on the bottom, and a ridged, notched scroll wheel made of aluminum alloy. The mouse feels sturdy and the metal scroll wheel makes it seem a little fancier — it definitely looks and feels pretty premium. I did think the side buttons felt like they were placed a little too far back, but after comparing the F01 Noctua Edition with other mice, the actual issue is that the side buttons are larger than average — and this results in the back button sitting further back on the chassis. It wasn't a dealbreaker, but I found it mildly uncomfortable.

The bottom of the mouse features two large PTFE mouse feet at the top and bottom, as well as a strip of PTFE around the sensor. There are five geometric cutouts surrounding the sensor, as well as the power button / DPI switch.

The mouse comes with a separate 8K polling dongle, which has two buttons (a programmable profile switch button and a DPI switch), and a 6-foot (1.8m) detachable, braided USB-C to USB-A cable. Both the dongle and the cable come in Noctua's signature colors (the dongle is brown and the cable has a beige fabric covering with brown accents).

Performance of the F01 Noctua Edition

The F01 Noctua Edition mouse features Pulsar's XS-2 optical sensor, which has a maximum resolution of 42,000 DPI and a maximum speed of 800 IPS, and can handle up to 70 G's of force. The mouse also features Pulsar's optical switches in its primary buttons (rated for up to 100 million clicks), and can get up to an 8,000 Hz polling rate. The sensor doesn't disappoint — its tracking was accurate and speedy in my tests, and it worked perfectly across a variety of surfaces (including glass). The only thing I can see affecting performance in this mouse is its weight — it's not heavy, but it's heavier than most of its competition.

As I mentioned earlier, at 73g the mouse is on the heavy side for an ultra-lightweight eSports mouse — and it's an entire ounce heavier than the fan-less version. I guess that makes sense considering... there's a fan inside it, but still. If you're looking for an ultra-lightweight gaming mouse and you're not particularly intrigued by the fan, there are lighter, cheaper mice out there, such as my favorite Razer DeathAdder V4 Pro, which weighs 56g and costs $169.99.

I'll admit I was a bit skeptical about the fan — I'm not really a person who suffers from sweaty palms while I'm gaming, however, so I'm aware I'm not the target audience. But as someone who is not the target audience, I have to say that the fan is actually pretty cool (pun intended). It's small, yes, but you can definitely feel it — and even though I don't sweat much, it still felt pretty good. The fan has four speeds, and the first two are practically silent. You can hear the two fastest speeds, but it's not particularly loud — you'll notice it, but those around you probably won't.

Activating the fan using the two side buttons and scroll wheel was easy enough, though the side buttons will activate when you press them, so it's not perfect. You can also turn on and adjust the fan speed in the software and/or you can program one of the buttons on the dongle to cycle through speeds.

If you do get sweaty palms while gaming, or you just happen to live and game in a hot environment, the fan in this mouse definitely works. It takes a toll on battery life, of course, but you can always plug it in. That said, that part of the mouse is practically non-existent, the holes are so big (it's even more full of holes than the Corsair Sabre v2 Pro Wireless MG). The structure of the mouse honestly keeps your hand — or at least your palm — pretty cool, even without a fan.

Features and Software of the F01 Noctua Edition

The F01 Noctua Edition is largely controllable via the hardware, which is nice. The fan can be activated and adjusted by holding down the two side buttons and scrolling, and DPI can be cycled through using the DPI switch button on the bottom of the mouse or the DPI switch button on the wireless dongle. The dongle also has a function button that cycles through onboard profiles by default — so you will need to connect to Pulsar's web-based peripheral software, Bibimbap, if you want to take advantage of this.

With Bibimbap — which you can connect to wirelessly — lets you remap keys (there are five programmable buttons, including the scroll wheel click) and has a built-in macro recorder. You can also adjust various settings, including DPI steps (up to 6), polling rate (ships with 1,000 Hz and goes up to 8,000 Hz), LOD or liftoff distance, and debounce time. You can also turn on the fan from this app, if you want. You can save up to five profiles directly on the mouse and cycle through them with the function button, or you can remap the function button to cycle through polling rate, LOD, debounce time, motion sync, turbo mode, and fan mode. That last one just does the same thing that holding down both mouse buttons and scrolling does, but it doesn't accidentally activate the side button functions.

Wireless Experience and Battery Life of the F01 Noctua Edition

The F01 Noctua Edition features two forms of connectivity: 2.4GHz wireless and wired (via USB-C). It doesn't have any RGB lighting, but it does have a built-in 40mm 5V PWM NF-A4x10 fan with four different speed settings. Oh, and an 8,000 Hz polling rate. Needless to say, its battery life varies quite a bit, depending on how you have it set up. Its built-in battery is 500mAh, which is... well, don't expect much when it comes to battery life. Based on my observations as I tested the mouse, I think you'll still be able to eke out a full day's worth of usage if you have the fan running at top speed, which is not a lot compared to most wireless mice, but not bad, considering.

Bottom Line

The F01 Noctua Edition is a very well-built lightweight gaming mouse, but its main selling point is definitely the built-in fan. And the built-in fan works pretty well — I was definitely impressed, even if I don't see myself using it very often (or at all, really). But if you don't need a mouse with a built-in fan, it's hard to recommend the F01 Noctua Edition over just about any other lighter, more affordable mouse, including Pulsar's own fan-free Feinmann F01. The Corsair Sabre v2 Pro Wireless, for example, weighs just 56g and has a shell full of holes, gets up to an 8,000 Hz polling rate and retails for $149.99.

Logitech Mobi Fold review

The Logitech Mobi Fold is, without question, the weirdest mouse I have ever used in my life.

This tiny, foldable travel mouse is focused on one thing above all: portability. Just like a clamshell phone from the noughties, it can fold in half, allowing you to easily slip it into your pocket if you’re working on the go. But even though the Logitech Mobi Fold’s exceptional portability is its clear USP, I have to ask… is it actually that necessary?

After all, a lot of mice are already highly compact, and if you’re working on the go, you’ve probably got a bag to hold your laptop or tablet, right? I’d bet that your bag can fit a laptop and a mouse, so arguably, the thing that makes this mouse so special isn’t actually that game-changing.

Still, the Mobi Fold has a few interesting features to run through, and you’re surely curious as to how such a strange model feels in use. So, after using the Logitech Mobi Fold as my main mouse for a few days, here’s how I’d rate it — and whether I think it can compete with the best mice around.

First things first, the Mobi Fold is incredibly easy to get set up. There’s a sync button on it that makes linking up to a windows laptop, Mac, or Android device incredibly seamless. There’s also an easy switch feature, making it incredibly speedy to flick between a range of devices.

But after I got set up with the Mobi Fold, and started using it to get some work done I have to say… it wasn’t amazing.

The Mobi Fold exhibits a few key issues that make it feel inferior to a standard compact or productivity mouse. First of all, it has a slightly bizarre build. Its V-shape form makes it feel awkward to grip, and when using it for extended periods, this caused me to feel some discomfort in my hand. It lacks the ergonomics of my everyday mouse, the Razer Viper V3 Pro, and even lacked its fluidity, meaning moving it across my desk felt clunky.

In addition, the touch-controlled scrolling is a bit inconsistent. It doesn’t provide the same tight control of a traditional mechanical scroll wheel, and again feels a bit lacking in terms of fluidity. Don’t get me wrong: it’s totally functional, but if you want the smooth, precise scrolling of a traditional mouse, the Mobi Fold may leave you wanting more.

My final critique is on the feel of the left and right buttons. While these are serviceable, they felt more stiff than I expected them to, especially towards the back and middle of the model. I did appreciate the muted sound of clicking the left and right buttons, but I wish they felt a bit more sensitive.

Despite all of this, there are some clear positives worth pointing out. First of all, the mouse offers great battery life. It supplies about 22 hours of continuous use, which easily got me through the work week, meaning I didn’t need to charge it at all during the testing period. Having said that, Logitech says that you can get an extra three hours of use from just one minute of charging, making it exceptionally practical for someone like me who often forgets to juice up their devices.

In addition, the Mobi Fold features customizable button controls through the Logi Options+ app. This enables you to adapt pointer speed, set the central touch panel to different functions (like paste, volume controls, or a keyboard shortcut), and more.

In terms of design, I’m also a fan of the rubbery texture of the mouse, which is very pleasant to the touch. It’s also worth noting that 36% of the plastics used in the Graphite colorway of the mouse I used are made from recycled materials. It’s 29% for the Lilac and Off-White variants, which look pretty stylish in my opinion.

Look, the Logitech Mobi Fold does well to stand out from the crowd. Its lightweight and foldable design undoubtedly makes it easy to travel with — even though I’d argue that standard mice are probably portable enough as they are. In addition, the customizable buttons, long battery life, and satisfying feel of the mouse are clear positives.

But for $79.99 / £69.99 / AU$129.95, the Mobi Fold ends up feeling like a relatively poor value for money option. Really, that comes down to one thing: its lackluster performance. With underwhelming ergonomics, as well as slightly stiff scrolling and buttons, the Mobi Fold feels like an idea that’s far more impressive in concept than it is in practice.

Logitech Mobi Fold review: price & release date

• $79.99 / £69.99 / AU$129.95
• Released in June 2026
• Available in four colors

The Logitech Mobi Fold released in June 2026, carrying a list price of $79.99 / £69.99 / AU$129.95. That price means it’s competing in the same price bracket as great models we’ve tested, such as the Keychron M6 8K, but a lot more than our favorite ultra-compact mouse, the Logitech Pop Mouse. It's available in four colors, including Graphite, Off-White, Lilac, and Sand.

How I tested the Logitech Mobi Fold

• Spent days using it as my main mouse
• Tried out its various features
• Took on the go to test its travel credentials

I spent multiple days testing the Logitech Mobi Fold, using it as my main mouse in the office and when working from home.

During my time with the Mobi Fold, I used it for general productivity, exhausted its various features, and even took it on the go to assess its on-the-go credentials. I typically had the mouse connected to my Windows PC, but I also tried it out with an Android phone.

More generally, I’ve spent years testing gadgets here at TechRadar, where I serve as an in-house Senior Reviews Writer. I’ve tried out a wide array of computing accessories, such as the Turtle Beach Command Series KB7 keyboard, as well as gaming gear, premium wireless headphones, power banks, and more.

Keychron, which is known for its mechanical keyboards, just launched a wireless trackball mouse designed to comfortably sit underneath your space bar, complete with six programmable buttons. The Nape Pro wireless trackball mouse is now available on Amazon for $89.99. Although it may look pricey, with comparable ergonomic trackball mice often priced significantly lower, its unique rectangular design makes it the perfect companion for programmers, writers, and those who primarily use the keyboard for productivity. The placement means you don’t have to lift your hands from the keyboard to move the cursor, although it will get in the way if you prefer using a wrist rest.

• Get the Keychron Nape Pro wireless trackball mouse on Amazon.

The keyboard maker revealed the quirky trackball mouse earlier this year at CES, and it’s finally available for those who are interested. It’s wireless, sports six customizable buttons and a control dial, so you can also use it as a macro pad that you can place to the left or right of your keyboard or drawing tablet (or even center, if you have a split keyboard) and pair it with one of the best gaming mice for regular use. But what makes the Nape Pro more useful and powerful is the customizability that Keychron offers. You can change the functions of each button and the dial on the trackball mouse to exactly match what you need. It also has up to seven layers, so you can change what each button does based on what you need.

There are other trackball mice available on the market, like the Elecom Huge Plus with its 52mm ball and 10 programmable buttons (by comparison, the Nape Pro only has a 25mm ball), but they’re mostly designed to replace your mouse with their ergonomic designs. The Keychron trackball, on the other hand, feels like it’s there to complement your current ergonomic mouse and not replace it entirely.

This trackball mouse is another unique product from Keychron, which is known for making one of the best wireless and best budget mechanical keyboards. The keyboard company also makes different types of mice for basic use, productivity, and gaming, but it seems that it hasn’t hit the home run yet on these models. Perhaps the Nape Pro, which is like a hybrid macro pad and trackball mouse, would help elevate its mice to the same level as some of its mechanical keyboards, like the Keychron K3 Ultra.

Simply put, polling rate is the frequency at which data is sent between your mouse and keyboard to your computer. For many years, the standard polling rate of most gaming mice and keyboards was 1,000Hz, and that's still a setting that's available by default.

However, with the rise of competitive shooters, particularly tactical ones such as CS2, VALORANT, and Rainbow Six Siege, the pro scene needed a shift, and we saw the advancement towards 4,000Hz and 8,000Hz for "esports tech".

The best gaming keyboards and the best gaming mice are marketed for their 8K or 8,000Hz polling rates, particularly in models aimed at esports pro players. If you look at the current gear in circulation, it's easy to see how it's caught on: the Razer Viper V4 Pro, and the Logitech G Pro X2 Superstrike are recent examples of pointers, and the Razer Huntsman V3 Pro Tenkeyless, Corsair Vanguard Pro 96, and Cherry XTRFY K63W Pro Compact Ultra-Wideband for decks that tout this feature.

But does anyone really need an 8,000Hz polling rate when gaming? Do the best FPS players in the world even take advantage of it? I'm going through everything you need to know about how 8K works, the latency you can expect, impact on battery life, and all other things you need to consider when properly getting your setup ready for success.

How does polling rate affect latency?

True to its namesake, an 8K polling rate will report its position to your PC a total of 8,000 times, instead of 4,000 times or a thousand times as with 4,000Hz and 1,000Hz, respectively. An 8,000Hz polling rate responds with far lower latency than either of these two previous standards; specifically, updates are sent between a mouse or a keyboard to your computer's processor every 0.125ms, eliminating a theoretical maximum of 0.875 ms input delay, meaning a smoother cursor or movement.

The difference in response time of 0.125ms (8K), 0.25ms (4K), and 1ms (1K) can be huge when it comes to polling rate, provided you have the right hardware to properly take advantage of this. That's because an 8,000Hz polling rate can be incredibly demanding on the battery life of wireless mice and keyboards, and it's one of the main considerations as to why you may want to drop the response time down in your settings.

The drawbacks of an 8,000Hz polling rate

In brief, an 8,000Hz polling rate for your mouse and keyboard can be incredibly demanding on your computer. That includes heavy strain on even the best processors, the aforementioned heavily reduced battery life on a mouse and keyboard, and even the potential risk of micro-stuttering. As a lifelong PC gamer and a competitive shooter enthusiast who is hopelessly obsessed with VALORANT, I've seen the battery life debate happen in real-time.

I've tested and reviewed hundreds of mice and keyboards throughout my career, and one of the biggest points of contention when it comes to enabling the polling rate comes down to battery life. As an example, my favorite gaming mouse of all time is the Corsair Sabre V2 MG, an 8K-enabled gaming mouse that's built with a Magnesium Alloy frame. It weighs just 56g and features excellent skates, making it ideal for a precision heavy shooter.

As standard, via the Corsair Web Hub, this gaming mouse will run out of the box at 1,000Hz (1K), with battery life prioritized. With the pointer used as the stock, you can expect around 100 to 120 hours of play between charges. In my experience, I am charging this mouse every two weeks or so, depending on how much I'm working day-to-day, etc. However, in my many months with this mouse, I've noticed that things fall off incredibly hard with 8K enabled; my battery life tends to last only around two to three days (or one or two nights of VALORANT Competitive) before I'm reaching for the USB-C lead.

If we take 18 hours as the average battery life from the Corsair Sabre V2 MG when used in 8K mode, that's a reduction of around 85%, which is staggering. We can see a similar drop off from the most well-used new esports mice currently on the market, with the Razer Viper V4 Pro (an excellent mouse), touting up to 180 hours of playback in 1K but only 45 hours when maxed out at 8K. Similarly, while the Logitech G Pro X2 Superstrike has around a 90-hour playback at 1K, that drops down dramatically to between 20 and 35 hours at 8K. With Logitech's pointer, though, you have to factor in the strength of the haptics here, hence the rough range rather than a more exact figure.

What about the human limitations of an 8,000Hz polling rate?

Now that we've covered what an 8,000Hz polling rate is, how it works, how it compares against 1K and 4K, and the technical drawbacks, we now need to go over the human limitations with 8K. As previously mentioned, 1K means a 1ms response time, and that gets cut down to just 0.125ms with 8K, but what does that mean for a human being, and not a machine?

The average human response time is around 250-280ms; that's the time it takes to see something and physically react. I am not a pro player, but I do play video games at a high level, with a response time average of around 175ms, though I've been faster. The best esports players can eclipse this effortlessly: you only need to look as far as VALORANT and CS2 players, such as TenZ (widely considered to be among the best VALORANT players), with an average reaction time of 135ms. 100ms is even possible, even though the average tends to hover around the 150ms mark.

If we take 1K as a baseline for polling rate, that means there's an average of 150 reports between the mouse/keyboard and the processor, as you tap a key or click what you see. Taking 8K, then, sees 1,200 instances. With this information in mind, is there really much of an advantage here, even at this granular level, with the best players in the world and, conversely, the only people who would even notice a proper difference between 1K, 4K, and 8K?

Do pro players use 8,000Hz polling rates?

Considering the far lower latency, you would expect that professional esports gamers would all dial their settings to an 8,000Hz polling rate by default when playing demanding games, but that's simply not the case. If we look back at TenZ's mouse and keyboard settings when playing VALORANT, he last used the Pulsar TenZ Signature Edition mouse at 1,600 DPI, 0.24 sensitivity, and (most crucially) a 1,000Hz polling rate as standard; no 4K, and certainly no 8K enforced here.

What about a VALORANT player from the most aggressive team in the game? Then we must look at f0rsakeN from the legendary Paper Rex. He was last using the Pulsar Sustanto-X with an 800 DPI, a 0.71 sensitivity, and a 4,000Hz polling rate. Let's move away from Riot Games' shooter and instead turn our attention to Valve, then. As far as CS2 players go, few are as well-regarded in 2026 as Team Spirit's donk.

The young Russian is widely regarded as the best player in the world. Is he using an 8K polling rate for his mouse and keyboard to do this? No, while he previously used the industry standard Logitech G PRO X Superlight 2, he's now switched to a bespoke, and as of yet unreleased/prototype Zowie X Donk mouse at 800 DPI, 1.25 sensitivity, and a 1,000Hz polling rate. What about Niko? He recently had his own Razer collaboration drop, and currently uses a Razer Deathadder V4 Pro Niko Edition with an 800 DPI, 0.9 sensitivity, and a 2,000Hz polling rate.

Let's briefly look at two games for the sake of argument, and two of their respective top players. Peterbot is widely considered the best Fortnite player in the world, and he uses a Logitech G Pro X Superlight 2 at 800 DPI with a 1,000Hz polling rate. ImperialHal is among the best Apex Legends players, and the CEO (as he's known) currently uses a Finalmouse Starlight Pro with an 800 DPI, a 1.1 sensitivity, and a 1,000Hz polling rate. So, pro players simply are not using an 8,000Hz polling rate when playing, and they're simply better than the other 99.9% of players who play these games.

Is using an 8,000Hz polling rate worth it?

Based on everything I've gone through here, it becomes challenging to wholesale recommend (or actively condemn) 8K. An 8,000Hz polling rate is mechanically and technically better for how it responds between the peripheral and the machine, even if the human who presses that key or clicks the mouse ends up being the limiting factor, or bottleneck. It's the simple, undeniable truth that the saved milliseconds are (really) indistinguishable to basically everyone on the planet.

Then we get into the debate of battery life. Do you want your gaming mouse to last over 100 hours on a single charge, or just 10? That's a tough sell, considering it undercuts the primary reason to cut the cord in the first place. Then there's the massive CPU overload, game engine incompatibility (and developers and publishers are not yet gearing their software for the tech), and the variables of the hardware itself. Hardware makes the difference: TMR and Hall Effect switches and sensors will have far more of an impact than the simple reporting time between the processor and peripheral.

So why am I not fully discouraging you from using an 8,000Hz polling rate in its entirety? Because it ultimately comes down to personal preference, and to feel. If you're running one of the best gaming PCs or best gaming laptops with a high-end processor, a 4K graphics card, and a high refresh rate monitor, then, battery life aside, it doesn't really hurt to have everything cranked up and forgotten about. Are you likely to really notice it? No, but fractional optimization is still (ever so slightly) better than none in the first place.

I'm not quite cynical enough to claim that an 8,000Hz polling rate is just a marketing gimmick; however, I will say that hardware companies have gleefully exploited the ignorance of the end consumer, the simple reductionist view that a bigger number automatically means better, without looking into the nuances of the conversation. Now that's something you will be fully clued up on when considering your next keyboard or mouse.
